The Stranger in the House

Christmas trees arrived in England and America only in the mid-19th century…

The Tannenbaum (which simply means “fir tree”) came to be associated, apocryphally or not, with Martin Luther. Because of that, many Catholics in Germany once disdained it. The “aversion of many Catholics went so far,” Mr. Brunner writes, “that at the end of the nineteenth century many simply called Protestantism the ‘Tannenbaum religion.’ ” As late as the 1930s, the Vatican was recommending manger scenes instead of Christmas trees as a more theologically sound sort of decoration. But the church today no longer sees a conflict—Christmas Eve at the Vatican’s St. Peter’s Square now features both a life-size Nativity and a towering Christmas tree.

It wasn’t until the middle of the 19th century that the tradition began to spread outside Germany. Christmas trees were a novelty in England by 1850, thanks to a royal example set by the German-born Prince Albert…In the mid-19th century, the Christmas tree made inroads in America, too…

There are a lot of non-Christian symbols associated with the celebration of what is now called Christmas. Tannenbaum literally means “fir tree” and is the German term for Christmas tree. Although Catholics once derided Protestants for the practice, the times I have been in Vatican City near Christmas, I have seen Tannenbaums there.

Most who have looked into the subject of Christmas trees are familiar with the passages in Jeremiah 10 that clearly condemn pagan tree practices:

2″Do not learn the ways of the nations
or be terrified by signs in the sky,
though the nations are terrified by them.
3 For the customs of the peoples are worthless;
they cut a tree out of the forest,
and a craftsman shapes it with his chisel.
4 They adorn it with silver and gold;
they fasten it with hammer and nails
so it will not totter.
5 Like a scarecrow in a melon patch,
their idols cannot speak;
they must be carried
because they cannot walk.
Do not fear them;
they can do no harm
nor can they do any good.” (Jeremiah 10:2-5, NIV).

While the trees themselves cannot harm us, God says that they cannot do any good.

Even though there is nothing in the Bible to encourage putting a tree in one’s house to honor Jesus or the Father, both Catholics and Protestants believe that they have a legitimate reason to.

Even though they condemned the fir trees when once calling Protestantism the “Tannebaum religion,” Catholics claim a prior use. In the 7-8th century, their St. Boniface chopped down an oak dedicated to Thor and a fir tree grew at the same place. After that happened Boniface was said to have stated, “Its leaves remain evergreen in the darkest days: let Christ be your constant light” (Christmas Tree. Wikipedia, 12/22/07). But the truth is that the evergreen tree had long been a pagan religious symbol in northern Europe.

Here is one account of the of how Catholics and Protestants got the tree:

hy do we have a decorated Christmas Tree? In the 7th century a monk from Crediton, Devonshire, went to Germany to teach the Word of God. He did many good works there, and spent much time in Thuringia, an area which was to become the cradle of the Christmas Decoration Industry.

Legend has it that he used the triangular shape of the Fir Tree to describe the Holy Trinity of God the Father, Son and Holy Spirit. The converted people began to revere the Fir tree as God’s Tree, as they had previously revered the Oak. By the 12th century it was being hung, upside-down, from ceilings at Christmastime in Central Europe, as a symbol of Christianity.

Now, getting back to the accusation of Catholics about Protestants being the “Tannenbaum religion,” basically the Protestants condemned the Church of Rome for many practices, including idolatry. The Catholics considered that having a decorated fir tree in one’s house, which of course is not a symbol associated with the birth of Jesus in the Bible, during the Christmas season was a form of idolatry.

However, over time, as the use of trees gained more universal acceptance, those of the Catholic faith decided to no longer decry their use, but instead found a legend in their own history to suggest that they had the idea originally.

All of this may seem to be bizarre, but a lot of the doctrinal history of the Catholics and Protestants is.
